7 Claims.

The present invention relates to improvements in cane pllers and more particularly relates to an attachment for cane harvesters constructed and adapted to pile the cane in windrows in accordance with a prearranged plan, as hereinafter more fully described.

In accordance with the present practice of harvesting sugar cane with mechanical harvesters Where the cane is planted in rows, the cane is piled parallel w-ith the rows, such practice being usually termed windrowing When the cane is so harvested hand labor is necessary to transfer the cane from the position parallel with the rows to a posi-tion across and at right angles to the rows, placing the cane from two or more rows into what is called a heap, in other words a heap row where it is subsequently picked up with conventional mechanical. cane loaders and loaded into wagons.

The reason that cane from two or more rows is placed into a heap pile or heap row, is to eliminate additional traveling by both the loaders and the wagons in the fields, which would be necessary if each row were piled separately, and to provide two clear or free rows through which loading and cane wagons may travel in loading and hauling cane.

It is an object of the invention to eliminate this hand labor and to in the first instance discharge the cane from the back of the harvester and place it crosswise the row instead of in the customary parallel position.

It is another object of the invention to accomplish this purpose by a simply constructed simple functioning 4attachment for a standard cane harvester which admits of the transfer of at least three rows of harvested cane onto a single heap row or heap pile."

The invention has for a further advantage that it allows the burning of shucks and trash in cane between the time it is mechanically harvested and the time it is loaded. This permits delivery to the processing mill of commercially clean cane without the necessity of manual handling. The method and device according to the present invention also eliminates the necessity of syn- 'chronizing mechanical harvesting with the loading and transport facilities. With the improved process and apparatus there is also eliminated the transfer of grass and weed growth in the transfer of cane to the heap rows.

With the foregoing and other objects in view the invention will be more fully described hereinafter and more particularly pointed out in the appended claims.

Figure 10 is a similar view showing the parts in position to harvest row 3, and

Figure l1 `is a cross section taken through the vframe of the attachment and its main conveyor and showing one of the arches.

Referring more particularly to the drawings, `3l) representsa cane harvester mounted on wheels 3| with the gathering endless chain conveyors v32 and 33 at its forward end leading to the spiral flight 5I on the rotary drum or scroll 52. This drum has threads on flights 5l that screw through the cane and draw the same to the rotary severing knife 54.

The proper location of the bottom severing 50 knife 5S is shown in Figures 2 and e; this arrangement is conventional in 'the art as shown by the Wurtele Patent 2,281,904, granted May 5, 1942. As the harvester moves forwardly the rotary knife 5d severs the stalks at the bottom.

The longitudinal conveyor 35 has projections 36 for receiving such cane stalks. The cane stalks are held between or against the projections 36 by a holding or pressure bar 3l. .At the rear delivery end of the conveyor is a delector oar N which may be a. continuation of the pressure the longitudinal conveyor 35. In Figure 4 this curved deflector bar N is shown in top plan view as being curved from the rear end of the pressure bar 31 in a wide sweepingcurve transversely of the harvester 30 and spaced back of the rear portion of the longitudinal conveyor 35 whereby the conveyor 35 releases the cane stalks to the curved deflector bar N in the normal forward movement of the cane harvester 30.

As shown in Figure 1 the deilector bar N is preferably made with a substantially horizontal portion 38 and a diagonal portion 39 and as shown in Figures 1 and 4, on the rst pass of the machine through the field over row I the deflector bar N receives the cane in an upright standing position with its severed butt end resting upon the ground on the top of row I and as the harvester 30 moves forward the curved deflector bar N, which engages about mid height of the cane stalks (Figure 1), induces those stalks to tilt laterally of the rows and to fall with the long axis of the cane stalks in `a direction transversely of the rows and transversely of the direction of movement of the cane harvester 30. The rear free end of the deector bar N is free and open for the passage and falling of the cane stalks except `when a rotary deilector bar M is made to extend across the throat which is formed between the rear end of the longitudinal conveyor 35 and the curved deiiector bar N, as hereinafter described and shown more particularly in Figure 8.

In the forward portion only of thisthroat projects the inner or receiving end of a iixed section I of a transverse conveyor. The transverse conveyor is made up of this fixed inner conveyor section I and the outer pivoted swinging conveyor section B.

The inner section I is composed of an endless chain 40 running substantially horizontally around sprockets 4I and 42. The sprockets may be carried by a suitable frame 43 carried by the rear end of the harvester by any suitable means for instance by the brackets 44. The chain may have suitable projections 45 which may be sharpened if desired as shown to advantage in Figures 4, 5, and 6 to bite into the cane barrels or stalks. A pressure or holding bar J is supported by an arched supporting member K substantially parallel and spaced back of the rear run of the endless chain 4I) to confine the stalks against such rear run of the chain which moves in the direction of the arrow in Figures 9 and 10.

The outer pivoted conveyor section I is carried by a cantilever or other type frame A which has a pivotal bearing 4B about an upright shaft or post D mounted upon the rear corner portion of the harvester vehicle 30. The frame A is adapted to swing about the shaft D, as compare Figures 4 and 5. The frame A carries a substantially horizontally running endless chain B running over sprockets 41 and 48. The chain B has projections 49 which may be of .the nat blunt form shown in Figures 9 and 10 or of the sharp pointed form shown in Figures 4, 5, and 6 to bite into the cane stalks or barrels.

Mounted in spaced relation rearwardly from the rear run of the conveyor chain B are two pressure or holding bars E and F. These holding or pressure bars E and F are endwise spaced apart to provide a gap 20 therebetween for the discharge of cane stalks. The end pressure bar F near the gap 20 is hollow to slidingly and rotatingly receive a shank I9 of a. diagonal deector bar L adapted in its outer position (Figure 10) to seat in a holding bracket I8.

The holding bars E and F are in alignment with one another and with the holding bar J when the outer conveyor section B is swung to the outstanding position shown in Figures 5 and 6.

The inner end of pressure or holding bar J is also hollow to rotatably receive a shank I5 on the defiector bar M. An oblique portion I6 extends inwardly from the shank I5 and a right angular portion I1 extends oli the oblique portion I6. The outer conveyor section frame A has a base O to which one end P of the arch G is afiixed thereto and supported thereby, thel other end Q of said arch G supporting the holding bar E which is spaced from the conveyor chain 1B, as best viewed in Figure 11. In a similar manner a pressure bar F is held in place by arches H, as shown in Figure 2; and the holding bar J of the inner fixed transverse conveyorsection is held in .place by other arches K. The space between the inner transverse conveyor I and its holding b ar J is operi at its inner end R and at its outer end S to permit the passage of cane through the conveyor I between the conveyor frame and the holding bar J as best seen in Figure 4.

The shaft D extends below the sleeve 46 and both sprockets 42 and 41 are afiixed thereto. In other words these sprockets 42 and 41 respectively of the conveyor sections I and B are axially aligned and fixed to rotate with the shaft D which may not only be a pivotal support for the outer swinging conveyor section B but also the power shaft by which both conveyors I and B are driven from suitable source of power X derived from the power plant (not shown) of the harvester 30.

The frame A for the outer conveyor section B is rotatable about the shaft D so that it may be folded in a manner indicated in Figure 4 alongside the vehicle 30 when noty in use or when the harvester is making the first .pass or run down row I. Or the frame A and swinging conveyor B may be swung out to the position indicated in Figures 5 and 6 where it extends at substantially right angles to the path of movement of the harvester and in alignment with the inner conveyor section I.

Figure 4 shows the relationship between the rear end of the harvester longitudinal conveyor 35, the curved Ydeiiector bar N and the inner or receiving end of the conveyor I and its holding bar J. It will be noted that the holding bar J is spaced forwardly of the.rear free end of the curved defiector bar N in order to form a gap 50 therebetween for the free falling movement of the cane stalks when the harvester is making the first pass over row I.

It will be understood that by reason of the axial alignment of the sprockets 42 and 41 that the endless conveyors I and B are overlapped at their'proximate ends whereby the rear runs of these conveyor sections act to continuously lmove the cane stalks in a generally upright posi--A tion transversely of the harvester in a direction to thefoff side of such harvester. By olf is meant the side of the harvester away from the standing cane. f

The cane stalks acquire considerable mo-- v,ally from the cutter 54 down the row being presently cut that the cane ls piled on` the heap row across row attingerel which necessarily travel I and row O as shown in Figures 2 and 3.

In the operation of the device, normally the v deector bar M is thrown out of the way and the frame A is swung or folded against the side of the machine, as indicated in Figure 4. This leaves the deilector bar N alone operative.

In piling cane harvested on row I, cane discharging from the harvester in a vertical position is thrown by deiiector bar N so that it drops across rows Il and I. This position is shown in Figures 1 and 4. Row Il is row 3 of the preceding cycle of three rows harvested.

In the next operation, shown in Figure 2, which involves the harvesting of row 2, the frame vA is swung at right angles to the direction of travel of the harvesting machine and defiector bar M is thrown into operating position. Defiector bars M and N cause the cane to fall into conveyor I. The cane is held between conveyor I and holding bar J and is carried at right angles to the travel of the machine. Upon reaching deiiectorbar L the cane is dropped out of the conveyor B, which forms a continuation of the conveyor I, and drops across rows 9 and I. This places the cane from the second row cut on top of the cane dropped from the first row. The inverted arch G trips the butts or lower ends of the cane so that the cane falls in a horizontal position.

In the next operation, illustrated in Figure 3, the defiector lever L is thrown so that in eiect it joins holding bars E and F into a continuous holding bar. This alteration makes this operation substantially the same as the operation over row 2. However, in this third operation the cane does not fall out of conveyor B until it reaches the end of the same. The length and proportions of this conveyor B are such that cane from row 3 is dropped on top of cane from rows I and 2. With the completion of the operations on row 3 the cane from rows 2 and 3 ,is piled with caneV from row I, and there are two free clean rows through which cane loaders and cane wagons may travel in order to load and haul cane. The cycle of three operations commences anew, row 3 of a preceding cycle becoming row Il of a new cycle.

Referring more particularly to Figures 7 and 8 the deilector bar M is shown as having a shank I5 rotatably mounted in the holding bar J which is tubular whereby to rotate between the two positions shown in Figures 7 and 8. In Figure '7 the intermediate oblique portion I6 of the defiector bar M substantially parallels the defiector bar N and the right angular portion I'I of the deiiector bar M closes the mouth of the conveyor I so that harvested cane follows deector bar N. When deflector bar M is rotated 180 towards the back of the machine, as 'illustrated in Figure 8, it closes off the exit of cane'along deilector bar N and deflects cane into conveyor I. This is the position for harvesting rows 2 and 3.

Referring more particularly to Figures 9v and 10, deflector bar L is ,a piece of shafting which both rotates and slides in Vpressure bar F which is a piece of pipe or tubing. When in position for harvesting row 2, deflector bar L is slid axially into pressure bar F and rotated toward the forward part of the machine so that the diagonal portion of the deflector bar L extends forwardly and it may rest on the top of conveyor B. In this .p osition, cane traveling between conveyor B and pressure bar E is dropped as it leaves pressure bar E.

For harvesting row l, deiiector bar L is slid toward the left side of the machine and rotated toward the back of the machine, its -diagonal portion being dropped into a slotted `bracket I8 attached to the end of pressure bar E. In this position the straight part I9 of deilector bar L forms a link between the pressure bars E and F and in effect joins same into a continuous pressure or holding bar.

Figure 9 shows the condition of the parts for discharging cane through the gap 20 between the holding or pressure bars E and F. In this case the straight part or shank I9 is telescoped into the tubular'pressure or holding bar F so as to remove the straight part I9 from the gap or opening 2li. The diagonal deflector bar L in this Figure 9 is arranged to intercept the cane stalks moved by the conveyor B and deflect the same out through the gap or opening 20.

Figure 10 shows straight part or shank I9 pulled out from holding or pressure bar F so as to bridge the gap or opening 20 while the deiiector bar part L is rotated away from conveyor B.

Thus the defiector part L does not interfere with the movement of the cane stalks from holding bar E to holding bar F and the straight part I9 forms a continuous holding or pressure bar across the, gap or opening 20 and compels the cane stalks to move out to the end of the conveyor B. Thus the straight part or shank I9 acts in the capacity of a sliding gate to open and close the gap or opening 20.

Figure 11 shows how the inverted arches G perform the double function of supporting the pressure or holding bars from the frame A and at the same time serve to engage the lower portions of the cane stalks.
